We deliver our 1:5 On-Road and 1:6 Truck models with standard air filter including factory oiled filter insert. This filter is sufficient for
the use on tracks with low formation of dust. To be on the safe side we recommend to change or rather clean the foam filter inserts and
oil them with the filter oil 06441. According to the higher formation of dust we standard equipped the 1:6 Off-Road models with the FG
Off-Road inlet air filter with oiled filter insert. Corresponding to the formation of dust you have to clean and oil the filter inserts of these
Off-Road filters, too.
Further inlet silencers, filter oils a.s.o. for FG models and other brands you will find in our main catalog on the pages 49, 132-135.
1. Fuel
For the correct fuel mixture we recommend to use Super Plus fuel together with a high-quality 2stroke oil f.e. Item N°. 08559 FG Panolin Racing
Oil. The mix ratio of the fuel ought to be around 1:25. Do not store fuel mixtures longer than 4-6 weeks as afterwards certain components of the
mixture may decompose. This could cause a reduction of the lubricating effect which results in higher wear and less power. First fill the oil into the
canister, then the fuel.
Mix ratio 1:25: 1Liter Super Plus - 40ml oil
5Liter Super Plus - 200ml oil
2. Initial operation of the engine
Before each starting up of the engine check the air filter on dirt and correct and firm seating. Test the engine for leaks at manifold, cylinder foot
and carburetor-insulator area. Should the engine be slightly greasy or damp we recommend to replace the gasket. The basic adjustment of the
engine is preset by the factory.
3. Starting the cold engine
Close the carburetor throttle valve and bring it into neutral position. Now shut the choke flap at carburetor or air filter (Zenoah G230/G260RC and
Chung Yang). Press the primer pump at the carburetor until it is filled with fuel. Pull the rope starter slowly until you feel the first resistance, then
pull strongly until the engine ignites audible. Normally the engine will die down again after the initial start. Now open the choke flap and pull the
rope starter once again until the engine runs.
4. Starting the warm engine
Keep the choke flap open, press the primer pump until it is filled with fuel and actuate the rope starter. To turn the engine off, press the stop but-
ton until the engine stops.
5. Carburetor adjustment
The carburetor adjustment is preset by the factory according to the local conditions. Depending on air filter, exhaust silencer and usage site a cor-
rection may be necessary. Operate the engine until it has reached its working temperature. If the engine decelerates a little during the accelerati-
on, then it runs too lean. In this case turn the no-load adjusting screw L (1/8 rotation) anticlockwise. If the engine revs up only slowly stammering
and under clouds of smoke, then the engine probably runs with an overrich mixture. In that case turn the no-load adjusting screw L (1/8 rotation)
clockwise. In order to adjust the maximum range of speed, lift the rear wheels and operate the engine under hot running conditions shortly at full
speed. Now you can turn the full-load adjusting screw H to the left (if the mixture is too lean) or to the right (overrich mixture).
ATTENTION! Operate the engine under no-load conditions only shortly at the maximum speed range. In most cases the no-load adjusting screw
has to be readjusted if the adjustments of the engine were modified.
6. Basic adjustment of the carburetor
The declared values are reference values. In some cases a re-adjusting may be necessary. If you have the feeling that the adjusting screws L or H
are completely misadjusted, then close both adjusting screws carefully in clockwise direction. Afterwards open both adjusting screws L and H
around 1,25 – 1,5 rotations anticlockwise.
Avoid maximum speed ranges under no-load conditions during the first two tank fillings and with a cold engine, also longer full-speed drives. Be-
fore the first operation we also recommend to check the effective radius of the radio control system with running engine. A disturbance through
the ignition system is possible. To suppress the interference we recommend to use our shielded spark plug cap Item N°. 07328/05.
Never operate the engine in closed rooms without sufficient ventilation. Further safety instructions are enclosed with the engines.
